I understand this action doesn't have the camming power of a mauser or other typical blot action, BUT, how may of you out there have actually had a failure to extract? Also, were you using GP11 ammo when it happened?

When you get a typo, try the "edit" button on your post. The system will let you go back & fix it. Pretty cool!

I haven't fired GP-11, only handloads. I've never had a stuck case, or an extractor that wouldn't grip the rim, or any other problem with extraction. Before I learned to work the bolt with conviction, I had occassional failures to go into battery, but that's operator error.

I think its more of a theroretical problem than anything else. Even in the dusty sandy desert near my home my k31's have never had difficulty chambering or extracting.

I have never had any problem with mine other than a spent shell smacking me on the noggin every now and then. Thats half the fun of it. Ive always used GP-11 and it works perfectly. Cant get enough of it.

I agree with this statement 100%. Pretty much all bolt, slide and lever actions require an authoritative stroke on the part of the shooter to work as designed. I would go so far as to say that this is really a skill that needs to be taught. I am amazed at how many shooters will "baby" a manual action and then complain about how rough it is, or how hard it is. I can understand that people don't want to be hard on the gun, but there is a big difference between being hard on a gun and working the action with conviction. Excellent point, IMO.

Never had a problem. If I'm not pulling the bolt back smartly, then the extracted case will flip around and lay on the next round to be fed. However, if you yank it and slam it (within reason), it will work perfectly. Don't baby it- it won't break. Don't beat the living tar out of it either- you just might break it.

both my K-31's have "never" had a ftf or fte yet.

do keep in mind if you handload for the K-31 all the reloading books list the OAL wrong.the K-31 has a short throat and the ogive of the bullet being used makes a difference when adjusting for the oal of the loaded round.

Same here, never a problem with my K-31.

Love the K-31. That trigger just glides.

Precaution:

I have an older model Ruger M77 which has the "push feed" mechanism.
If you have it or one similar; not the "mauser" guided round mechanism;
-then you must be certain that you have not over-ridden a round from the magazine and are chambering a second round upon a preceeding one! Operating the bolt briskly is good, but be sure you do not vigorously close the bolt, with another round, upon a chambered round that is waiting there.

I had read a more concise explanation here before. Can anyone word this better? Or simpler.

I have 18 Swiss straight bolt action rifles, I have never had an ejection problem with any of them. They all eject the shells fine, better than some of my Mausers.

as usual, some great real-life data that is greatly appreciated. also, another example of a problem with a valid basis for anticipation but, alas, no hard facts, as of yet, to back it up.

That can also be a reloader error. If I don't keep the full-length sizer die low enough, the case shoulder will make it hard to chamber. Also, if I only neck-size a Win284 case, it absolutely won't chamber, again the shoulder needs to be pushed back a little.

The extractor on my K-31 is amazing. I should put a bowl on the top of my head; that would help me catch 90% of my brass.

Like everyone else, here, I have never had a FTE with my K-31.

It has never had GP-11 ammo. Just reformed .284Win handloads. And the .284Win rim is just a touch smaller than the 7.5 Swiss rim. So, you'd think that with 7.5 Swiss ammo, it would be EVEN more reliable. If that were possible.

LOL, Casper...I know what you mean, After getting a few on the head and 1 hot one down my shirt, I tilt the rifle to the right upon ejection.:D

It seems, at least on mine, it takes quite a bit of force to uncam the bolt on the K-31. I suppose that's to be expected on a straight pull gun. So what happens is when it breaks loose is it really flings the brass! I agree an authoritative motion working the action is in order, and it's probably more noticable on the K-31 as you have to put all the force straight back and straight forward. Certainly not enough though to be considered much of a hinderance for what was a combat rifle.

If extraction is a problem i would check the extractor for wear and tension as well as chamber cleanliness and condition. Personally i've never had a problem with extraction and GP-11.
